Hi, after I bought the Lenovo Ideapad 500S with Windows 10 pre-installed, a Linux OS was installed. Now, I want to change it again to Windows 10. I made a bootable USB (with Linux), changed the settings in BIOS to EUFI and tried to boot. He's giving me 2 options; HDD and the USB after restart. But he won't boot from the USB... If I click on it, the screen flickers and returns to the same position. When i made the bootable USB, i've noticed that the name has changed. Any suggestions?
